Batriscenellus strictus Jiang and Yin View in CoL , new species
( Figs 8 View FIGURE 8 B, 9B–C, 9F–G)
Type material (2 exs). Holotype: ♂: ‘ China: S. Zhejiang, Qingyuan (mỄH), Baishanzu N. R. (UƜdzŊĖOiṖ Ữ), path nr. hotel, 27°44'42"N, 110°10'19"E, leaf litter, sifted, 30.iv.2014, 1060–1130, Peng, Song, Yan & Yu leg.’ ( SNUC) GoogleMaps . Paratypes: 1 ♂, same collection data as the holotype (SNUC).
Diagnosis of male. Dorsal surface of the head, pronotum, and tergite IV finely punctate; antennomeres elongate; elytra with relatively shallow sutural and discal striae; profemora strongly constricted near apex, mesotibiae with small apical projection; abdominal tergites unmodified; aedeagus with short ventral lobe, and with much longer, preapically expanded and apically curved and narrowed dorsal lobe.
Description. Male ( Fig. 8 View FIGURE 8 B). Body reddish-brown, length 2.05–2.06 mm. Head subrectangular, slightly wider than long, HL 0.41–0.42 mm, HW 0.45–0.46 mm, dorsal surface finely punctate ( Fig. 9 View FIGURE 9 B); vertex with complete median ridge, connecting to anterior margin of U-shaped sulcus that connects foveae; antennomeres elongate, clubs formed by apical three antennomeres; each eye composed of about 35 facets. Pronotum about as long as wide, PL/ PW 0.47–0.48 mm, finely punctate ( Fig. 9 View FIGURE 9 B). Elytra wider than long, EL 0.70–0.72 mm, EW 0.78–0.80 mm, narrowed at base, discal striae shallow and slightly curved, extending to apical 4/5 of elytral length; sutural striae complete. Profemora ( Fig. 9 View FIGURE 9 C) strongly constricted near apex, mesotibiae each with a small apical projection. Abdomen wider than long, AL 0.45–0.46 mm, AW 0.71–0.72 mm, finely punctate and with short setae; tergites lacking modifications. Aedeagus ( Fig. 9 View FIGURE 9 F–G) strongly asymmetric, length 0.32 mm, ventral lobe short, broad at base and narrowed toward apex, dorsal lobe much longer than ventral lobe, strongly expanded preapically, strongly curved apically and narrowing toward apex.
Comparative Notes. Batriscenellus strictus is placed in the B. uenoi group based on the simple abdominal tergites of the male. All three known species of the group, i.e., B. uenoi from Japan, B. femoralis Yin & Li (in Yin et al. 2011) from Zhejiang, eastern China, and B. hongkongensis Yin & Wang (in Wang et al. 2015) from Hong Kong, southern China, have modified metafemora. By contrast, B. strictus has apically constricted profemora of the male, and thus can be readily separated from the three above-mentioned species.
Female. Unknown.
Distribution. Eastern China: Zhejiang
Etymology. The specific epithet strictus refers to the preapical constriction of male profemora.
